Cleaned up a lot... it's all not in folder 'old'.
I kept a my_vector_shifter.m file in folder +tools for maybe using it later on, bit probably
it'll not be used as I am thinking of another way of doing a selection of the regressors
to be used for removing movements from the EEG.

Next step is to work on the diagnistocs/selection part...
Small fix to have the window disappear (and not have it in the screen all the time) when matlab'll do the removal.
